I'm sure this must have been asked before but I can't find another question, so I guess I'll just answer :-)

comment How to destroy file contents without deleting files
@Ramhound: that's ridiculous. The software to do this might not have been already written, but it's almost trivial to write (though a little more than a one-liner in most programming languages). Of course there is a way to query the size of a file and write exactly that many zero (or random) bytes to it!

comment Running a Command in xterm Without the Window Closing
The command you are trying to execute doesn't make much sense: it will start a shell under the user user2, and then after the user quits that shell, it will uselessly source a .cshrc file before exiting. Did you mean so source that file inside user2's shell instead?

comment OSX - Using different DNS for different network interface
Think about this: how is it supposed to know BEFORE making a DNS query which interface is going to be ultimately used to forward packets that go to the address that is going to result from the DNS query. Hint: this is easy to solve if you have a time machine for predicting the future.

revised How to edit a remote file with implicit su-ing to another user on remote host
I know this is counts as minor, but I find starting a question with "So" very off-putting, like jumping into the middle of a conversation

comment How to make Thunderbird play nice with Google mail
This is not at all a problem between Thunderbird and gmail. It's a problem between IMAP and gmail. IMAP has no concept of tags and it has no concept of the same message existing in multiple folders. Google has no way of communicating to Thunderbird (or any other IMAP client) the fact that two messages in two folders are in fact the same message. There are only two ways around that: use a different protocol than IMAP that supports this, or use an IMAP protocol extension that supports this (if there existed one).

comment How does TCP get the MSS values for a certain path?
Not necessarily, because the traffic might follow a different route in each direction, and the 2 paths might have different MTUs. However, I'm not 100% sure, but I think TCP makes the assumption that it is symmetric (i.e. it negociates to the lowest value). Making that assumption won't do any harm.

comment Firefox can't find the file at sip: xxxx
That's very odd because Firefox should either (1) offer to launch an application or do something special if it understands the sip: URI scheme, or (2) give the error message "The address wasn't understood" if it doesn't have knowledge of the sip: URI scheme. Under no circumstances should it try to treat the URI as a file! What is the exact value of the hyperlink you are clicking on to get this error, and how is it generated (is it in an HTML page?)?

comment File shows different size after copying to another directory
FWIW and in contrast to some of the prior comments, du -k lists kibibytes, not some arbitrary filesystem-dependent block size. Different filesystem block sizes are not the direct cause of this issue. That being said, filesystems are allowed to store files however they want, using however much (or little) space as they deem suitable, and there never is any guarantee that a copied file takes the same amount of storage space as before. There are all sort of filesystem-specific reasons why the copy could take more space, but a good first suspect is that the original file may have been sparse.

comment Need IMAP client that does not wait and wait and wait for confirmation that copy was put in Sent folder
In other words the client sends the command to save a message to a folder (which is an IMAP APPEND command) and the IMAP server simply doesn't reply at all to his command? That would be a protocol violation on the part of the server and it would not be surpising for many or most IMAP clients to have dificulty tolerating that. That Rackspace's IMAP server would be violating the protocol like this sounds fishy.

comment How to rename to existing folder
@kumarM I don't know... I guess there had to be something already existing inside the deployables_05_14_2013 directory but no matter what I try I cannot reproduce the "subdirectory of itself" error message. As for the rename command, I was unfamiliar with this command but I read the manpage. It looks like you are using it incorrectly: the first argument is supposed to be a Perl substitution command, not a filename.

comment How to rename to existing folder
@terdon It may be natural in spoken English where you say the name of the month, but I don't find it natural at all in writing. On a more objective note, the biggest flaw of this format is that it is probably going to get misinterpreted whenever the day number is 12 or less (because it looks like a month number). The workaround for this is to use the month name instead of number... which is exactly what is done in speech.
